Adobe Photoshop Lightroom 3 (for Windows: XP, Vista & 7)

    This is my primary image organization, global and limited local adjustment program. The workhorse in my stable. Once you have done your correction/enhancement work - be it a raw, psd, jpg or tiff image file - you’ll select the images you want to resize and put them either a permanent or temporary collection (like “Smart Collections”). You’re not actually moving the file from it’s location(s) on your hard drive(s), just telling Lightroom that you have an image stored somewhere that you want to do something to at sometime.

Adobe Photoshop Lightroom 3 - Export - Screen Capture - CLICK FOR ENLARGED VIEW    Open your collection and highlight the images you want to resize. Then click the “Export…” button in the lower left corner. A new dialog box will appear and in the upper left corner it will let you know how many images you are going to export (example: “Export 10 Files”). In the main window, there are numerous options indicated by a gray bar. If the option section is open, the little gray arrow to the left of the option title is pointed down. You can close this section (or open it) by clicking on that little arrow.

    “Export location” is where you will navigate/browse your way to where you want to save the resized images to (a new folder at some other location, same location where the images came from, etc.). You can even add these resized images to your existing catalog if you choose to. “File Naming” is one I skip for this type of resizing due to the fact that each image needs a different name depending on the competition’s naming convention.

    “File Settings”, now we’re getting into the meat of it. “Format:” is “JPEG” and “Color Space:” will be sRGB. I don’t move the “Quality:” slider because I’m going to check the “Limit File Size To:” box and type in “350” in the “K” box (without the quotes of course). Checking the “Include Video Files” box doesn't hurt anything here as everything I’m exporting is still images (your choice, on or off).

    “Image Sizing”. Check the “Resize to Fit:” box and select “Long Edge” from the drop-down menu. I leave the “Don’t Enlarge” box clear as everything I’m resizing is taking a large file to a smaller one. Type in “768” (no quotes) into the box and select “pixels” from the drop-down menu. “Resolution:” defaults to “240” and “pixels per inch” (in the drop-down). It does not matter where these numbers are as it is irrelevant for our use. We care about how many pixels by how many pixels - resolution is just for printing.

    “Output Sharpening”. I will turn-on the “Sharpen For:” box and select “Screen” from the first drop-down menu and “High” from the “Amount:” one. “Metadata”, “Watermarking” and “Post-Processing” I tend to leave in the default settings though I may check the “Write Keywords as Lightroom Hierarchy” in the “Metadata” section if I am keeping these resized images in my Lightroom Catalog. Also feel free to look at the other settings, even if you are not going to change anything at this time. If you think you will be using these particular export settings a lot, you may want to save them as a “Preset” by clicking the “Add” button in the lower left (under the “Preset” window).

    Now that everything is set, click the “Export” button and voom-de-la-voom (watch the progress bar in the upper right corner of the main Lightroom interface window) - your images have any Lightroom (and/or Camera Raw adjustments from Photoshop proper) applied, they’re resized, converted to jpg, compression/quality is set not to exceed the sweet 350kb file size and they’re stored in the location of you choice just waiting for you to rename them according the competition you’re entering’s naming convention. Done!

    Note: not all of the programs listed above can open/manipulate every type of image file, although all should work on jpeg image files. You will need to research yourself if you can use said programs with your image files.
